Corten weathering steel exterior wall processing
| Processing Method | Common Specs / Parameters | Notes / Considerations |
|---|---|---|
| Sheet Thickness | 1.5–6 mm | Common façade thickness: 2–4 mm. Thicker sheets resist wind load better but cost more. |
| Cutting | Laser cutting accuracy ±0.1 mm Waterjet cutting accuracy ±0.2 mm |
Laser cutting recommended for complex shapes; waterjet is better for large panels to reduce heat effects. |
| Bending | Minimum inner bend radius = thickness × 1–2 | Bending angles up to 180° possible; risk of cracking must be considered. |
| Welding | Stick welding or TIG | Welds naturally develop rust patina, but initial runoff should be managed. |
| Perforation | Hole diameter 3–20 mm Spacing ≥ 2× hole diameter |
Holes smaller than 3 mm are difficult to drill and may clog; design must balance aesthetics and ventilation. |
| Surface Treatment | Pre-rusting 2–4 weeks (accelerated patina) Sandblasting 60–120 grit |
Controls rust uniformity and early rust streaks. |
| Panel Size | Max width 1500 mm Max length 6000 mm |
Adjust for transport and installation limits; large panels can be installed in sections. |
Corten Weathering Steel Façade Processing Price Reference
(USD/m², excluding installation and transport)
| Processing Method | Price Range (USD/㎡) | Notes |
|---|---|---|
| Flat Cutting (Laser / Waterjet) | 28–56 | High precision; complex patterns cost more; thicker and larger panels are more expensive. |
| Bending / Pressing | 21–49 | Simple bends are cheaper; small-radius or complex bends cost more. |
| Welding / Assembly | 14–35 | Price depends on weld length and sheet thickness; complex structures increase cost. |
| Perforation | 35–70 | Smaller holes and higher hole density increase cost; artistic patterns are more expensive. |
| Surface Pre-Rusting / Sandblasting | 7–28 | Sandblasting cost depends on grit and panel area; pre-rusting requires additional time and space. |
| Complete Façade Assembly | 70–167 | Includes cutting, bending, welding, and surface treatment; complex shapes or large areas increase cost. |
If you want a highly durable and long-lasting building façade, appreciate its unique rustic-modern style, and plan a project that minimizes future maintenance costs, Corten metal cladding is an ideal choice.

Is Corten cladding expensive?
Although corten steel may seem more expensive at first, it is a smart choice in the long term as it lasts longer and requires little maintenance. The price difference between traditional steel and corten steel is minimal. Corten steel is more expensive due to the materials used and the specialized production process.
How long will corten steel last outside?
Generally, Corten steel will patina or rust within six months of atmospheric exposure. Most weathering steel types need wet/dry weather cycles to develop and oxidize. With the protective rust that provides corrosion resistance, Corten steel can last upwards of a few decades to over 100 years.
What does corten steel look like before it rusts?
While many select corten, or weathering steel, because of its practical benefits, others select the steel for the appearance of its rusty, orange-brown patina. However, weathering steel is silver in its original state – just like standard steel. The patina develops over time when exposed to weather
How thick is a Corten panel?
The Corten is available in thicknesses from 22 gauge up to ½" thick in a variety of lengths and widths, which makes it compatible with any type of project
